When a user builds the mobile communication high security application system shown in fig. 1, cloud negotiation of network security key parameters, such as IMSI identification (International Mobile Subscriber Identification Number, international mobile subscriber identity) representing the identity of the mobile subscriber, a network access authentication algorithm, etc., is required on the control plane, and related parameters are also changed according to policy requirements. The traditional mode is that the main authentication enhancement service at the network side prepares the security parameters to be changed according to the strategy, then the network side waits for the terminal to initiate the network access authentication request, carries the parameter change control instruction in the network access authentication downlink authentication vector, and the security USIM card (Universal Subscriber Identity Module, global user identification card) deployed at the mobile terminal executes the parameter change.
The method can complete the safety parameter change only when the terminal needs to passively wait for network access, and the terminal cannot complete the safety parameter change all the time in the network or in the service state, so that the real-time performance is poor and the change time is not controlled. Meanwhile, when a user judges that the security risk exists and needs to adjust the security parameters in the process of using the terminal, the user does not have a better technical means and can timely inform the network side, and the risk of insufficient security exists.
